Is the partitioning based on the first(leading) column of the index? In my experience - don't know if it's a fixed rule - a local partitioned index is not being used unless the partitioning column is among the predicates. Having said that, I haven't had a chance to possibly revise that experience with Oracle 9.2 or 10.
